Metabolic Pathways Quiz

Exercise Physiology and its History

• Exercise Physiology is defined as the study of the physiological responses and adaptations that occur during exercise or physical activity.
• Hippocrates is considered the 'Father of Modern Medicine'.

Energy Systems

• The energy system with the highest capacity and longest duration is the oxidative system.
• The energy system that produces ATP quickly and has a high rate/power is the phosphocreatine system.
• The energy system that is not easily fatigued is the oxidative system.
• The energy system with the lowest inertia and quickest recovery is the phosphocreatine system.

Muscle Fibers and Glycolysis

• Type I muscle fibers are more predominant in LDH1-2.
• The end product of glycolysis is pyruvate.
• The enzyme responsible for the conversion of pyruvate into lactate is LDH (Lactate Dehydrogenase).

High-Intensity Exercise and ATP

• The main source of ATP during high-intensity exercise is the phosphocreatine system.

Famous Physiologists and Their Contributions

• Claude Bernard is typically acclaimed as the greatest physiologist of all time.
• William Harvey discovered continuous blood circulation.
• Karvonen is best known for a method to predict optimal exercise training heart rate, the so-called 'karvonen formula'.
• The equation for relative risk of mortality vs Energy is not provided in the text.

Hierarchical Structure of the Nervous System and Blood Circulation

• René Descartes proposed the hierarchical structure of the nervous system and observed the heart as a muscle 'pump'.
• William Harvey discovered continuous blood circulation.

Anatomical Knowledge and Treatises

• Leonardo da Vinci accurately rendered bones, muscles, nerves, internal organs, and blood vessels in a treatise.

Energy Systems and Metabolism

• The three energy systems involved in metabolism are the phosphocreatine system, the glycolytic system, and the oxidative system.

Creatine-Phosphate Shuttle and ATP

• The equation for the reaction between PCr and ADP is not provided in the text.
• The role of the creatine-phosphate shuttle is to facilitate the rapid diffusion of PCr and Cr across the cell.
• The role of ATP in cell diffusion is to provide energy for the cell's various activities.

PCr Levels and Exercise

• PCr levels decrease during exercise.

Importance of Exercise Physiology

• Three reasons to study Exercise Physiology are not provided in the text.
